Application led December 9, 1914. Serial No. 876,343.

To all whom zt may concern.'

Be it known that we, GEORGE BATY and ROBERT M. RYAN, said BATY being a subject of the King of Great Britain, said RYAN a citizen of the United States, said BATY residing at Brooklyn, in the county of Kings, and said RYAN residing at New York, county of New York, 'both in the State of New York, have invented a new and useful Incandescent Gas-Burner, of which the following is a specification.

This invention relates to an incandescent gas burner and more particularly to a burner of the inverted type.

It has been heretofore customary to sup-v port the mantle and shade of an inverted burner upon the burner tube, with which arrangement it is impossible to obtain access to the burner without first removing the shade and the mantle therefrom. This op eration frequently results in the destruction of the delicate mantle and also involves a considerable expenditure of time and labor in separating and reassembling the parts. Furthermore, it is necessary that the burner should be within the mantle when lighted. The mantle thus becomes filled with gas and upon ignition an explosion of considerable force occurs, which places an excessive strain upon the delicate structure of the mantle.

It is one of the objects of our invention' to provide an incandescent gas burner of the type described in which the burner tube may be removed from its operative position relative to the mantle without first removing the latter from its normal position. B this construct-ion we are enabled to light the burner while removed from the mantle to a position in which the flame may be readily inspected and adjusted and we also avoid explosive injury to the mantle.

A further object of our invention is to provide an improved mantle holder by the use of which the mantle may be readily removed from its operative position for inspection or cleaning. We also provide a single support for the mantle holder, the shade and the reflector so designed that any one of these parts may be removed without disturbing the other two parts.

A still further object of our invention is the provision of an improved pivotal conmoved from its operative position relatively to the mantle and byV which the pilot flame will be extinguished as the burner is returned to operative position.

We also provide an improved arrangement for passing the pilot tube through the Bunsen burner.

With these objects in view our invention comprises certain devices, arrangements, and combination of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of our invention is shown in the drawings in which` 1 Figure 1 is a side elevation of an inverted incandescent gas burner embodying the several features of our invention; Fig. 2 is an enlarged front elevation, partly in section, of the Bunsen tube and its pivotal connection to the supporting pipe; Figs. 8 and 4 are transverse sectional views taken along the lines 3-3 and M of Fig. 2; Fig. 5 is a detail side elevation looking from the rear in Fig. 2 and showing the device for regulating the pilot flame; Fig. 6 is an enlarged detail view of the mantle holder; Fig. 7 is a side elevation of the burner tip; Fig. 8 'is a transverse sectional View `taken along the line 8-8 in Fig. 7 and Fig. 9 is a partial sectional view taken along the line 9-9 in Fig. 2.

Referring tol Fig. l we have shown our improved burner mounted upon a rigid pipe 10 having a valve 11 of any usual form connected thereto. An arm 12 is rigidly supported upon the pipe 10 and extends horizontally therefrom. At its outer end the'arm 12 is bent upwardly and supports a horizontal plate 13 which may if desired be formed integrally therewith. The plate 13 is provided with a plurality of depending projections 14 through which extend screws l5 for engaging and supporting a shade 16.

Upon its upper side, the plate 18 is provided with a plurality of fingers 17 which constitute means for supporting a reflectorV 18. A ring or band 19 of thin sheet material may encircle the armslt, being secured thereto and concealing the upper edge of the shade 16.

rIhe plate 13 is pro-vided with a central circular recess 2O within which is supported the mantle holder 21. rl`he holder 21 (Figs. 1 and 6) comprises a mantle ring 22 to which the mantle 23 is bound or otherwise secured. From the ring 22 a plurality of outwardly inclined arms 24 project upwardly in position to contact with the edge of the circular recess 20. At their upper ends the arms 24 may be connected by a reinforcing connection 25. The holder 21 is self-centering in the recess 20 and by changing the angle of the arms 24, a number of different sizes of mantles may be held in the same plate 13.

The burner tube 26 is pivotally connected to the rigid pipe 10, the outer end of the tube being initially movable upwardly in a substantially vertical direction out of the mantle l23 and thereafter movable about its pivot to the position indicated in dotted lines in Fig. 1. Vhen the burner is thus removed, it will be seen that the mantle 23 and its holder 21 may be removed from their support by simply lifting them through the recess in the plate 13. It will also appear that the shade 16 can be removed downwardly and that the reflector 18 can be removed upwardly without disturbing either of the other elements.

A iianged plate 27 of the usual form may be provided upon the burner tube to par tially cover the opening in the reflector 18 and the tube 26 may also be provided with a suitable burner tip, one form of burner tip suitable for use with a pilot light being shown in Figs. 7 and 8. Referring to said figures, the burner tip 28 comprises a substantially cylindrical wall 29 of magnesia or other suitable heat resisting material, said wall haring a small passage 30 extending longitudinally therethrough at one side of the cylinder and communicating at its lower end with a narrow slot 31 extending transversely through the wall. At its upper end, the passage 30 connects with the end of a pilot ube 32. This form of burner tip possesses distinct advantages even when used upon a fixed burner tube of the usual form. rlhe pilot `flame being within the mantle and at the edge of the burner tip, the inflowing gas is immediately ignited and the danger of explosion within the mantle is greatly rduced. Furthermore by the location of the longitudinal passage within the wall of the tip we provide an entirely unobstructed gas opening through the tip and by extending the slot transversely through the wall a portion of the pilot flame is positioned at the outer side of the tip where it cannot be eX- tinguished by the rush of gas through the tube. V

Referring to Figs. 1 and 2, we have shown the burner tube 26 connected to a Bunsen tube 33, of a well known type. This Bunsen tube comprises a substantially conical shell 31 having a small opening 35 at the upper end thereof. rlhe pointed upper end 36'of a sliding plug 37 projects into the opening 35, the amount of such projection being determined by the regulating screw 38. A spring 39 `may be provided within the shell 34: to force the plug 37 dow wardly against the regulating screw.

The enlarged lower end of the plug 37 is provided with a plurality of notches or recesses 4f() (Fig. Ll) through which gas may pass to the opening 35. ln our improved burner, we extend the pilot tube 32 (Figs. 7 and 2) around the curve of the tube 26 and enlarge one of the notches 40 to permit the passa o'e of the tube therethrough.

A lug or screw 11 may be mounted upon the side of the Bunsen tube 33, projecting within the burner and coaeting with a vertical groove 42 in the side of the plug 37, this arrangement permitting vertical move ment of the plug but preventing angular movement, thereby securing the plug in position to permit the free passage of the tube 32. The pilot tube extends downwardly through the Bunsen tube 33 and is designed to have a close sliding fit into a cylindrical passage t3 (Fig. 2) in a sleeve la which constitutes one element of the pivotal connection between the Bunsen tube 33 and the fixed pipe 10. rllhe Bunsen tube 33 is also designed to have a close sliding lit upon the outside of a cylindrical projection on the sleeve la and may be secured in position thereon by a serew passing through the lower end of the burner and into a hole in the sleeve. With this construction, the parts may be assembled by a straight axial movement which will permit the easy insertion of the pilot tube 32 into the passage a3.

lt is sometimes desirableto use the pilot flame as a night light, for which purpose the size 'of the flame should be increased. To permit easy adjustment of the pilot flame for either purpose we provide the screw yl5 having a handle i7 and engaging either one of a pair of stops i8 adapt-ed to position the handle in either the full line or tliedotted line position shown in Fig. 5. The stops i8 may consist of eocentrically mounted disks which may be adjusted upon their1 pivot screws -l-.9 for fine adjustment of the flame. The screw l@ extends into and partially closes the passage 43 (Fig. 9).

In the preferred form of our invention we provide special fitting for supporting the sleeve Il and the Bunsen tube 33 upon the pipe 10. Referring to Figs. 2 and 3, this fitting comprises a casting 50 threaded or otherwise fixed upon the pipe 10 and having a vertical passa-ge 5l communicating with a tapered opening 52 extending transversely through the upper end of the casting. A plug 54 provided with oppositely tapered ends is fitted into the opening 52 in the casting 50 and into the transverse opening in the sleeve 44.

The plug 54 is retained within the casting 50 by a screw 55 which engages a washer 56 and forces the same into frictional contact with the end of the casting 50. The washer 56 may be conveniently provided with arms 57 to which chain pulls 57a may be attached for purposes to be described. At the opposite endk of the plug 54 a screw 58 engages a washer 59 and forces the same against the end of the sleeve 44. The washers 56 and 59 are slidable but non-rotatable upon the end portions of the plug 54. In the actual operation of the device, the screws 55 and 58 are so adjusted that the friction between the washer 56 and the casting 50 shall exceed the friction between the washer 59 and the casting 44.

The plug 54 is provided with a central passage 60 communicating at its right hand end with a transverse passage 6l opening into a circumferential groove 62. At its opposite end the passage 60 is closed by a suitable plug or by the screw 55 and connects with a second transverse passage 68. This passage is so positioned that when horizontally diposed, as in Figs. 2 and 8, no gas can pass through the passage 68 to the central passage 60 and therefore no gas can pass to the Bunsen tube. When the plug 54 is turned 90 degrees from the position shown in Fig. 2 gas will pass freely through the passages 68, 60 and 61 and the groove 62 to a vertical passage 64 in the sleeve 44, the passage 64 opening into the gas chamber below the adjustable plug 87 of the Bunsen tube 88. The plug 54 is also provided with two smaller circumferential grooves 65 and 66 which are connected through the body of the plug by a longitudinal passage 67 suitably closed at its outer end by a plug 68.`

The groove 65 is positioned to communicate at all times with the. opening 5l` in the casting 50, while the groove 66 communicates with the passage 48 in the sleeve 44 through which connection is made with the pilot tube 82. When the plug 54 is positioned as shown in Fig. 2, gas will pass freely through the groove 65, the passage 67 and the groove 66 to the passage 48 and tube 82, thereby permitting the operation of the pilot light or night light when the main Bunsen tube is shut o.

It is desirable that the pilot light should be extinguished after the Bunsen flame is ignited, in order that a clear colorless flame may be secured and accordingly we interrupt the groove 66 by a closed portion or stop 70 which in certain positions of the plug 54 covers the lower end of the passage 48 through which gas is admitted to the pilot light.

In order that the plug 54 may be moved t0 admit gas to the Bunsen tube when the tube 26 is moved into the dotted line position shown in Fig. l, we provide the sleeve 44 with a lug 71 projecting into a recess 72 in the casting 50, and we also provide a pin 7 8 mounted in the plug 54 and engaging the upper side of the lug 71. When the burner is thrown back to its dotted line position, the lug 71 will move upward, as viewed in Fig. 2, carrying with it the pin 78 and turning the plug 54 through an angle of 90o. This movement of the plug allows the gas to pass through the Bunsen tube for ignition at the burner tip by the pilot light. After the burner is thus lighted, it is returned to its normal position within the mantle but the plug 54 remains unmoved by this latter movement on account of the excessive friction between the washer 56 and the casting 50. The sleeve 44 therefore turns relatively to the plug 54, and the stop 70 is thereby brought into position to cover the passage 48 and shut oftl the pilot light. The burner thereafter remains lighted until the plug is restored to its first position by proper manipulation of one of the chain-pulls 57a attached to the arms 57. It will thus be seen that the lighting of the burner and the shutting olf of the pilot light are accomplished by merely moving the burner out of its normal position and thereafter returning it thereto.

While this automatic operation of the different valves is of great importance it will be evident that many of the advantages of our invention do not depend upon the employment of this specific mechanism. For example, in a cheaper form of our device, we will omit the pilot light and will control the gas supply entirely by the valve 11, in which case any common form of hinged gas connection may be substituted for the connection shown in Fig. 2.
